TMD-分解、分解破缺与演化

TMD-factorization, Factorization Breaking and Evolution

S. M. Aybat, T. C. Rogers

摘要:

本文综述了微扰QCD因子化定理在涉及横动量相关(TMD)部分子分布函数(PDF)和碎裂函数(FF)过程中的应用现状。我们列举的情况下,TMD因式分解是行之有效的,并提到的情况下,它可能会失败。我们讨论了最近的进展,在具体的TMD分解计算,包括实施的演变。我们也给出了一些计算困难部分的例子。最后,我们讨论了未来的策略,实现TMD因子分解的现象学应用。

英文摘要:

We give an overview of the current status of perturbative QCD factorization theorems in processes that involve transverse momentum dependent (TMD) parton distribution functions (PDFs) and fragmentation functions (FF). We enumerate those cases where TMD-factorization is well-established, and mention cases where it is likely to fail. We discuss recent progress in the implementation of specific TMD-factorization calculations, including the implementation of evolution. We also give examples of hard part calculations. We end by discussing future strategies for the implementation of TMD-factorization in phenomenological applications.
